In TDMQ for Pulsar, a namespace is a logical isolation unit that helps organize and manage topics, producers, consumers, and other resources within a Pulsar cluster. It provides a way to group related entities together, enabling fine-grained access control, resource management, and configuration at a scoped level. Namespaces are essential for multi-tenant environments, where different teams or applications need to share the same Pulsar cluster while maintaining isolation.

Key Features of Namespace:

  1. Resource Isolation: Separate configurations (e.g., retention policies, quotas) can be applied to different namespaces.
  2. Access Control: Permissions can be granted or restricted at the namespace level.
  3. Multi-Tenancy Support: Different teams or applications can use the same cluster without interfering with each other.

Application Scenarios:

  1. Multi-Tenant SaaS Platforms: A SaaS provider can use namespaces to isolate data and configurations for different customers. For example, Customer A’s messages are stored in the customer-a namespace, while Customer B’s messages are in the customer-b namespace.
  2. Microservices Architecture: Different microservices can use separate namespaces to avoid topic conflicts and manage their own message retention policies.
  3. IoT Applications: Devices from different regions or customers can be grouped into separate namespaces for better management and monitoring.

Example:

A logistics company uses TDMQ for Pulsar to manage messages for its delivery tracking system. It creates two namespaces:

  • package-tracking: For messages related to package delivery status.
  • fleet-management: For messages related to vehicle tracking and maintenance.

Each namespace has its own retention policy and access permissions, ensuring that package-related data is isolated from fleet-related data.

For such use cases, TDMQ for Pulsar on Tencent Cloud provides a fully managed, scalable, and reliable messaging service, ensuring high performance and low latency for distributed applications.
